International Mail Processing Centres
International mail processing centres (IMPCs) are mail processing facilities that have significance for the processing of inter-administration mail, either because they generate or receive despatches or because they act as transit centres for mail exchanged between other IMPCs.
Please refer to UPU Technical Standard S34 for detailed information.
